Indicators in the Citation impact, Journal impact and Co‑publishing tabs are based on Web of Science publications only. Corresponding Scopus indicators can be found under the Scopus tab.

Overall Web of Science coverage for peer reviewed publications in this unit is moderate, 66.6%.

Note that the coverage numbers for Web of Science and Scopus apply to publications in the KTH bibliometric database Bibmet. If a WoS-id or Scoupus-id from DiVA can not be matched in Bibmet, it does not count as covered.

Background

The bibliometric indicators referred are based on publications registered in DiVA. Only publications from currently employed researchers at KTH are included. The rolling nature of this report means that it provides more of a current overview and less of a historic stable trend, since it excludes publications written by researchers that are no longer affiliated to KTH, but have been at some point in time.

The Open Access type of the publications was fetched from the Unpaywall REST API. The method to determine the OA type is presented here.

In summary, the different OA types can be described as follows:

  • Gold: The full text has been found on a publisher website, in a journal that is fully OA.

  • Hybrid: The full text has been found on a publisher website, in a journal that is not fully OA.

  • Green: The full text has been found in an institutional repository, such as DiVA.

  • Bronze: The full text has been found on a publisher website but no OA license could be identified.

N.B.: This table is based on peer-reviewed publications for which Unpaywall could determine the OA type (necessary condition: have a DOI number). Unpaywall’s method is empirical and does not strictly equate to copyright license. As a consequence, the OA status of a given publication may vary with time — for example turning from “Not OA” to “Green” when a full text is added to DiVA.
